Oceanic fronts represent important areas aggregating foraging seabirds, however, fronts can also act as barriers, possibly influencing their distribution patterns. Here, we investigated how fronts and environmental variables may drive the spatial distribution of seabird assemblages in the Southwestern Atlantic and Southern Oceans. Additionally, we tested if assemblages of seabirds fit into previously proposed biogeographical classifications, as these may work as surrogates to monitor assemblages. Seabird counts were carried out in November and March (2002, 2003, 2012). Sea surface temperature and salinity, bathymetry, chlorophyll-<i>a,</i> and the mean location of the Antarctic Circumpolar Current (ACC) fronts were used for the analysis of species composition. We used model-based multivariate methods to access differences in species composition across previously proposed biogeographic classifications. Model-based ordinations suggested no perfect fit of seabird species composition to these biogeographic classifications, with a high degree of overlap among their categories. However, multivariate generalised linear models indicated differences among them. Pairwise comparisons among biogeographic categories suggested differences in species composition resulted from categories to the north and to the south of the Antarctic Polar Front—<i>Thalassarche melanophris</i>, <i>Procellaria aequinoctialis</i> and <i>Macronectes giganteus</i> occurred in higher numbers to the north, whereas <i>Pygocelis</i> penguins and <i>Thalassoica antarctica</i> occurred only to the south. The results suggest that not all fronts in the ACC play a role in seabird distribution. Therefore, depending on the spatial scale of analysis, fronts do not necessarily dictate the biogeographical patterns of seabirds.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Spatial distribution of seabirds between the Southwest Atlantic and Southern Oceans: do all oceanic fronts influence seabird biogeography?","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-03 01:32:18.946865","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Albatrosses · Antarctic Circumpolar Current · Assemblages  · Community · Petrels","OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2025-06-12","DateCreate":"2025-06-12","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00300-024-03309-x"},"refs":null,"anarec":{"AnaID":408358,"PubliDate":2024,"Pagination":"1377-1390","XtraPublOfAnaID":null,"ISBN":null,"Volume":"47","Issue":"12","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43637,"SerRR":"Polar Biology.
